Cox IPv6 enablement of gateway modems

Saw this thread over on DSLR, and since it might come up over here, thought I would spread the word.Though if you know what IPv6 is...why are you using a gateway? 

Macon, GA: Cisco, Netgear, and Arris gateways are already dual-stacked. Ubee gateways will be enabled on or about 3/15/2016.
Omaha, NE: Ubee gateways are already dual-stacked. All other Cox-supplied gateways will be enabled on or about 4/12/2016.
San Diego and Santa Barbara, CA: All Cox-supplied gateways will be enabled on or about 3/29/2016.
Northern VA, Florida, Arizona, Louisiana, and Oklahoma: All Cox-supplied gateways will be enabled on or about 4/12/2016.
Kansas, Arkansas, Nevada, Rhode Island, Connecticut, Ohio, Orange County CA, Hampton Roads and Roanoke VA: All Cox-supplied gateways will be enabled on or about 4/26/201

Great info, Teck, thanks.  Looks like IPv6 is working here in Connecticut.  I know what IPv6 is so I obviously don't use a gateway

Just a note:
- Android doesn't support DHCPv6.  Since 5.0(Lollypop) it supports ND-RDNSS but no DHCPv6.  If you are configured to assign LAN addresses via DHCPv6, it won't work with Android devices.  With my Netgear Nighthawk router, I had to select "IP Address Assignment = Auto Config".  When I had it set to "Use DHCP Server" my Windows 10 and iOS devices worked but my Android phone (Marshmallow) didn't pick up an IPv6 address.

Really? I thought phones have been using IPv6 for traffic for a while, since this saved them from having to buy into the IPv4 space. Is this what you mean ND-RDNSS vs DHCPv6? Can you educate me on ND-RDNSS? Or maybe can acquire IPv6 from cellular network but not Wifi?

Anyone in GA with a gateway able to confirm? Did the options just become available? Just start to work? Or is it doing it invisibly from the UI, like a bridge?

I'm talking about WiFi only.  Cell data does pickup an IPv6 address, I don't know how since I don't have control over how 4G connects.  I do have control over my router so I can see what's happening via it's settings.  WiFi on my Android phone didn't pickup an IPv6 address when I had the router set for DHCPv6.  Here is a list in IPv6 support by OS: https://en.m.wikipedia.org/wiki/Comparison_of_IPv6_support_in_operating_systems

Yea, seems Android thinks: "Implementing stateful DHCPv6 would break planned use cases such as IPv6 tethering (which would require implementing IPv6 NAT in order to work with DHCPv6) and 464xlat.."  Too bad. Not that I need IPv6 on my cell phone, but for simplicity sake over the network. I wanted to try some performance testing on dual stack vs IPv6 only.
